Generate Key File Existing Database
If you want to convert your website from HTTP to HTTPS, you need to get a SSL certificate from a valid organization like Verisign or Thawte. You can also generate self signed SSL certificate for testing purpose.
In this article, let us review how to generate private key file (server.key), certificate signing request file (server.csr) and webserver certificate file (server.crt) that can be used on Apache server with mod_ssl.
Creating entity & context classes for an existing database is called Database-First approach. EF Core does not support visual designer for DB model and wizard to create the entity and context classes similar to EF 6. So, we need to do reverse engineering using the Scaffold-DbContext command. Dec 09, 2009 KeePass will generate a key file for you if you don't specify an existing file. A key file cannot be changed, this will stop you opening the database. You can save the database with a new key file. Key files must be backed up or you won't be able to open the database after a hard disk crash. Crt and key files represent both parts of a certificate, key being the private key to the certificate and crt being the signed certificate. It's only one of the ways to generate certs, another way would be having both inside a pem file or another in a p12 container.
Key, CSR and CRT File Naming Convention
I typically like to name the files with the domain name of the HTTPS URL that will be using this certificate. This makes it easier to identify and maintain.
Adding a Table to An Existing Database. You want the id column to be the Primary Key. Click the PK check box. Then click the Create Column icon to create another column. Select File Export DDL File. OR, you can select the Generate DDL icon. Click Generate. The simplest usage is to reflect an existing database into a new model. We create a new AutomapBase class in a similar manner as to how we create a declarative base class, using automapbase. We then call AutomapBase.prepare on the resulting base class, asking it.

- Instead of server.csr, I use www.thegeekstuff.com.csr
- Instead of server.crt, I use www.thegeekstuff.com.crt
1. Generate Private Key on the Server Running Apache + mod_ssl
First, generate a private key on the Linux server that runs Apache webserver using openssl command as shown below.
The generated private key looks like the following.
2. Generate a Certificate Signing Request (CSR)
Using the key generate above, you should generate a certificate request file (csr) using openssl as shown below.
3. Generate a Self-Signed SSL Certificate
For testing purpose, you can generate a self-signed SSL certificate that is valid for 1 year using openssl command as shown below. /arma-2-free-cd-key-generator.html.
You can use this method to generate Apache SSL Key, CSR and CRT file in most of the Linux, Unix systems including Ubuntu, Debian, CentOS, Fedora and Red Hat.

4. Get a Valid Trial SSL Certificate (Optional)
Instead of signing it youself, you can also generate a valid trial SSL certificate from thawte. i.e Before spending the money on purchasing a certificate, you can also get a valid fully functional 21 day trial SSL certificates from Thawte. Once this valid certificate works, you can either decide to purchase it from Thawte or any other SSL signing organization.
This step is optional and not really required. For testing purpose, you can always use the self-signed certificate that was generated from the above step.
Go to Thwate trial certificate request page and do the following:
- Select “SSL Web Server Certificate (All servers)” under the “select your trial certificate”.
- Do not check the PKCS #7 check-box under the “configure certificate”
- Copy/Paste the *.csr file that you generate above in the textbox under “certificate signing request (CSR)”
- Click on next at the bottom, which will give you a 21-day free trial certificate.
Copy/Paste the trial certificate to the www.thegeekstuff.com.crt file as shown below.
